Description
The ebmpapst R4E400-AB23-05 is a high-performance 230VAC single-phase AC Centrifugal Fan featuring 6 backward-curved blades with an Impeller Size of 400 mm and overall Dimensions of 404 x 404 x 162 mm. Specifically engineered for mission-critical industrial ventilation and air handling units, this unit is driven by the M4E074-EI external rotor motor with maintenance-free ball bearings and an 8.0 µF / 400 VDB (P0 CE) capacitor connection. Operating on a 230 VAC 50 Hz supply, it delivers a Power Input of 270 W and a Current Draw of 1.2 A at a rated speed of 1300 RPM under running at free air (fa) conditions. Featuring a rugged aluminum sheet impeller joined by tabs and a black coated rotor surface, it ensures superior thermal management with IP44 protection, F1-2 humidity class, and an extended service life in continuous S1 environments at the end.
